What increases molar solubility?

Solubility is affected by multiple factors. Solids becomes more soluble as temperature increases. As pressure increases, gases become more soluble. The common-ion effect describes a decrease in solubility of an ionic compound when the solution already contains an ion that is the same as one from the compound.

What represents the solubility of a compound in an aqueous solution?

You can determine which compounds are the solutes and which are the precipitates by using solubility rules (meaning solubility in water) or a solubility table. The solutes will be soluble, and therefore will be in aqueous solution, as indicated with the symbol (aq) written after the chemical formula of the solute.

What is the relationship between KSP and molar solubility?

A substance’s solubility product (Ksp) is the ratio of concentrations at equilibrium. Molar solubility, which is directly related to the solubility product, is the number of moles of the solute that can be dissolved per liter of solution before the solution becomes saturated.

What is the difference between solubility and molar solubility?

Solubility is the amount of solute that can dissolve in a given amount of solvent before the solution becomes saturated. Molar solubility is the number of moles of the solute that can dissolve per litre of solution before the solution becomes saturated. EXAMPLE. The density of a saturated NaCl solution is 1.202 g/mL.

Which compound has the greatest molar solubility in water?

Calcium fluoride (CaF2) has the greatest molar solubility in water.

How does common-ion effect influence solubility and solubility product?

If you have a solution and solute in equilibrium, adding a common ion (an ion that is common with the dissolving solid) decreases the solubility of the solute. This is because Le Chatelier’s principle states the reaction will shift toward the left (toward the reactants) to relieve the stress of the excess product.

How does common-ion effect affect KSP?

Adding a common cation or anion shifts a solubility equilibrium in the direction predicted by Le Chatelier’s principle. As a result, the solubility of any sparingly soluble salt is almost always decreased by the presence of a soluble salt that contains a common ion.

What is the difference between molar solubility and KSP?

Molar solubilityis the number of moles of a substance (the solute) that can be dissolved per liter of solution before the solution becomes saturated. It can be calculated from a substance’s solubility product constant (Ksp) and stoichiometry. The units are mol/L, sometimes written as M.
